Do you have an old airplane motor? Do you have a car radio? Do you have another $45.00? Is there a pond, puddle or large pool around? If you can say yes to all of these then my suggestion is go to Tower Hobbies, and get one of these! It is SO MUCH FUN! It isn't a race boat, it isn't a hydroplane, but it sure is fun for everyone. It will hold a turn at full throttle like no other boat. Acceleration is fair, but top speed is awesome with the right motor/prop combo. This is one of those things you take to the water with all of your friends, and you can let them drive it without fear of damaging your prize boat.
